Add architecture support for the MN10300/AM33 CPUs produced by MEI to the
kernel.This patch also adds board support for the ASB2303 with the ASB2308 daughter
board, and the ASB2305. The only processor supported is the MN103E010, which
is an AM33v2 core plus on-chip devices.[akpm@linux-foundation.org: nuke cvs control strings]

This adds the OMAP1 PWL-based LCD backlight driver. It's been in the OMAP
tree for some time. Note that OMAP2 can do similar things with the generic
timers which have PWM outputs. Such timers are more generic than the PWL
found on OMAP1 chips, but have a different EMI profile because they aren't
driven by a pseudorandom number generator.[akpm@linux-foundation.org: cleanups]

The current attr_fgcol_ec / attr_bgcol_ec macros do a simple shift of bits
to get the color from vc_video_erase_char. For a monochrome display
however the attribute does not contain any color, only attribute bits.
Furthermore the reverse bit is lost because it is shifted out, the
resulting color is always 0.This can bee seen on a monochrome console either directly or by setting it
to inverse mode via "setterm -inversescreen on" . Text is written with
correct color, fb_fillrects from a bit_clear / bit_clear_margins will get
wrong colors.Signed-off-by: Thomas Pfaff

On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from
the LCD controller. It's controlled by "contrast" registers though.This patch lets boards declare that they have that kind of backlight
control. The driver can then export this control, letting screenblank and
other operations actually take effect ... reducing the typically
substantial power drain from the backlight.Note that it's not fully cooked
- doesn't force backlight off during system suspend
- the "power" and "blank" events may not be done right
This should be easily added in the future.[nicolas.ferre@atmel.com: remove unneeded inline and rename functions]

Avoid displaying garbage on unused framebuffers. For most users a single
framebuffer is used together with fbcon. sm501fb supports two framebuffers
where one often is assigned to fbcon and the other one is left unused during
the boot.The problem here is that framebuffers not in use by fbcon happen to display
garbage. This can easily be solved by making sure that framebuffer memory and
palette ram are cleared.The problem can be observed by using looking at the panel output (fb1) after
booting the kernel with fbcon on crt (fb0). This is the default
configuration. It's also possible to watch the garbage on the crt framebuffer
by passing "fbcon=map:1" on the kernel cmdline. This will assign fbcon to the
panel (fb1) and leave the crt (fb0) unused.Signed-off-by: Magnus Damm

This patch makes it possible to control panel pins usage with flags passed
from the platform data. Without this patch the sm501fb driver always controls
the VBIASEN and FPEN pins. The polarity and use of these pins are very
platform specific, so this patch introduces the flags
SM501FB_FLAG_PANEL_USE_VBIASEN and SM501FB_FLAG_PANEL_USE_FPEN which enable
the use of these pins.This patch is needed to support the a Sharp LQ104V1DG21 lcd panel on SuperH
platforms such as R2D-1 and R2D-PLUS boards. Letting the sm501fb driver
control the FPEN and VBIASEN pins like today just results in lcd panel
flicker.Signed-off-by: Magnus Damm

The current nvidiafb_check_var() simply bails out if the selected mode is
out of range of the panel dimensions. A good question would be why the
bogus mode is being selected in the first place -- the panel dimensions
that are read back are certainly bogus, but alas, I have no idea where to
even begin looking at the i2c/EDID/DDC mess:nvidiafb: Device ID: 10de0165
nvidiafb: CRTC0 analog not found

nvidiafb: Panel is TMDS
nvidiafb: unable to setup MTRR
nvidiafb: Flat panel dithering disabled
nvidiafb: PCI nVidia NV16 framebuffer (64MB @ 0xC0000000)In my .config I presently have:
CONFIG_FIRMWARE_EDID=y
CONFIG_FB_DDC=y
CONFIG_FB_NVIDIA_I2C=yI've not tried fiddling with these options, as I haven't the vaguest idea
what I should be looking at.As a workaround, simply groveling for a new mode based on the probed
dimensions seems to work ok. While it would be nice to debug this further
and sort out why the panel information is bogus, I think it's still worth
retrying the mode based on the panel information at hand as a last-ditch
effort, rather than simply bailing out completely.Signed-off-by: Paul Mundt
